A set of CuxMg0.7-xAl0.3(OH)2(CO3)0.15.mH2O hydrotalcite-like compounds were synthesized by the co-precipitation technique at a certain pH. The synthesized samples have been characterized by some physical means of XRD, FT-IR, TEM, EDS and BET prior to use as a catalyst for the liquid oxidation of styrene with aqueous tert-butyl hydrogen peroxide (TBHP) oxidant. The synthesized samples show good hydrotalcite structure and with the presence of Cu(II) ions in layered Mg-Al hydroxides. Under similar reaction conditions, MgCuAl-CO3 layered double hydroxide catalysts exhibited good activity and high selectivity towards styrene oxide (75% selectivity at 73% styrene conversion) as compared with the MgAl-CO3, CuO/MgAl-CO3, and mixed oxides of MgCuAl-O.
